[gmx-users] Protein is Jumping from water Box

[Abid Channa]

Dear Gromacs users,
I have run 40 ns simulation , after 20 ns simulation my protein is continuously jumping from water Box. Is there any periodic boundary conditions issue with my system or an other error is that . Kindly give your valuable remarks.
Thanks,
Regards,
